FIELD OF THE INVENTION

The present invention relates to compositions comprising at least onepolyorganosiloxane-containing polymer, at least one volatilenon-silicone oil, at least one alkylene polymer wax, at least onesilicone film-forming agent and, optionally, at least one long-chainalcohol wax, at least one coloring agent, and/or at least one volatilesilicone oil, as well as to methods for using such compositions and tokits containing such compositions.

DISCUSSION OF THE BACKGROUND

Many pigmented cosmetic compositions such as foundations, lipsticks andmascaras have been developed for longer wear and transfer resistanceproperties. This is typically accomplished by the use of ingredientsthat form a film after application, ingredients such as silicone filmforming agents. Such compositions generally contain volatile solventswhich evaporate on contact with the skin or other keratinous tissue,leaving behind a film or layer comprising waxes and/or resins, pigments,fillers, and actives.

In the past, it has been problematic to formulate compositionscontaining silicone film forming agents such as silicone resins intocompositions possessing acceptable cosmetic properties such as, forexample, acceptable wear, transfer-resistance, feel, spreadability andstability properties, particularly where the composition was a solidcomposition such as a lipstick or a stick foundation.

Thus, there remains a need for improved compositions containing siliconefilm forming agents such as silicone resins, particularly solidcompositions containing such silicone film-forming agents, which haveacceptable or improved wear, transfer-resistance, feel, spreadabilityand/or stability properties for application to keratin materials such asskin, lips or eyelashes.

Accordingly, one aspect of the present invention is to provide a careand/or makeup and/or treatment composition for keratinous material suchas the skin, hair and/or lips, which is able to address or overcome atleast one of the aforementioned problems with the prior artcompositions, as well as to provide methods for using such compositionsand kits containing such compositions.

SUMMARY OF THE INVENTION

The present invention relates to compositions, preferably long wearingor transfer-resistant make-up compositions, comprising at least onepolyorganosiloxane-containing polymer, at least one volatilenon-silicone oil, at least one alkylene polymer wax and at least onesilicone film forming agent. Preferably, the compositions furthercomprise at least one long-chain alcohol wax, at least one coloringagent, and/or at least one volatile silicone oil. Most preferably, thecompositions further comprise both at least one coloring agent and atleast one long-chain alcohol wax.

The present invention also relates to methods of treating, caring forand/or making up keratinous material (for example, skin) by applyingcompositions of the present invention to the keratinous material in anamount sufficient to treat, care for and/or make up the keratinousmaterial.

The present invention further relates to covering or hiding skin defectsassociated with keratinous material (for example, skin) by applyingcompositions of the present invention to the keratinous material in anamount sufficient to cover or hide such skin defects.

The present invention also relates to methods of enhancing theappearance of keratinous material (for example, skin) by applyingcompositions of the present invention to the keratinous material in anamount sufficient to enhance the appearance of the keratinous material.

The present invention further relates to compositions having improvedcosmetic properties such as, for example, improved long wear, transferresistance and/or waterproof properties. The compositions may alsopossess improved flexibility, wearability, drying time and/or retentionas well as reduced tackiness and/or migration over time.

The present invention also relates to kits comprising a composition,preferably a long wearing or transfer-resistant make-up composition,comprising at least one polyorganosiloxane-containing polymer, at leastone volatile non-silicone oil, at least one alkylenene polymer wax andat least one silicone film forming agent, preferably further comprisingat least one coloring agent, at least one volatile silicone oil and/orat least one long-chain alcohol wax. Such kits can also includeadditional compositions such as, for example, topcoats for applicationto long wearing or transfer resistant make-up compositions or primers(basecoats) for application to keratin materials prior to application ofa long wearing or transfer resistant make-up composition.

It is to be understood that both the foregoing general description andthe following detailed description are exemplary and explanatory only,and are not restrictive of the invention.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the expression “at least one” means one or more and thusincludes individual components as well as mixtures/combinations.

“Film former” or “film forming agent” as used herein means a polymerthat, after dissolution in at least one solvent, leaves a film on thesubstrate to which it is applied, for example, once the at least onesolvent evaporates, absorbs and/or dissipates on the substrate.

“Transfer resistance” as used herein refers to the quality exhibited bycompositions that are not readily removed by contact with anothermaterial, such as, for example, a glass, food, an item of clothing orthe skin, for example, when eating or drinking. Transfer resistance maybe evaluated by any method known in the art for evaluating such. Forexample, transfer resistance of a composition may be evaluated by a“kiss” test. The “kiss” test may involve application of the compositionto human lips followed by “kissing” a material, for example, a sheet ofpaper, after expiration of a certain amount of time followingapplication, such as 2 minutes after application. Similarly, transferresistance of a composition may be evaluated by the amount of producttransferred from a wearer to any other substrate, such as transfer fromthe neck of an individual to a collar after the expiration of a certainamount of time following application. The amount of compositiontransferred to the substrate (e.g., collar, or paper) may then beevaluated and compared. For example, a composition may be transferresistant if a majority of the product is left on the wearer, e.g.,lips, neck, etc. Further, the amount transferred may be compared withthat transferred by other compositions, such as commercially availablecompositions. In a preferred embodiment of the present invention, littleor no composition is transferred to the substrate. Thus,transfer-resistant compositions include transfer-free compositions.

“Long wear” compositions as used herein, refers to compositions where atleast one property chosen from consistency, texture, and color remainsthe same as at the time of application, as viewed by the naked eye,after an extended period of time, such as, for example, 1 hour, 2 hours,and further such as 8 hours. Long wear properties may be evaluated byany method known in the art for evaluating such properties. For example,long wear may be evaluated by a test involving the application of acomposition to human skin (including lips) and evaluating theconsistency, texture and color of the composition after an extendedperiod of time. For example, the consistency, texture and color of a lipcomposition may be evaluated immediately following application and thesecharacteristics may then be re-evaluated and compared after anindividual has worn the lip composition for a certain amount of time.Further, these characteristics may be evaluated with respect to othercompositions, such as commercially available compositions.

“Make-up composition” as used herein means any composition applied tokeratin materials for aesthetic purposes. Examples of acceptable make-upcompositions include, but are not limited to, lip compositions such aslipsticks, liquid lip colors, lip glosses, skin compositions such asstick foundations or compact foundations, fingernail compositions suchas nail polish and eyelash/hair compositions such as mascaras.

The compositions, kits and methods of the present invention cancomprise, consist of, or consist essentially of the essential elementsand limitations of the invention described herein, as well as anyadditional or optional ingredients, components, or limitations describedherein or otherwise useful in personal care compositions intended fortopical application to keratin materials.

The compositions of the present invention may be in any form. Forexample, they may be a paste, a solid, a gel, or a cream. They may be anemulsion, such as an oil-in-water or water-in-oil emulsion, a multipleemulsion, such as an oil-in-water-in-oil emulsion or awater-in-oil-in-water emulsion, or a solid, rigid or supple gel,including anhydrous gels. The compositions can also be in a form chosenfrom a translucent anhydrous gel and a transparent anhydrous gel. Thecompositions of the invention may, for example, comprise an external orcontinuous fatty phase. The compositions may be anhydrous. In anotherembodiment, the compositions of the invention may be transparent orclear. The compositions can also be a molded composition or cast as astick or a dish. The compositions in one embodiment can be a solid suchas a molded stick or a poured stick. The composition can be either solid(for example, a lipstick, a stick foundation or a compact foundation) orliquid (for example, a liquid lip composition, mascara, liquidfoundation or nail polish). Also, the composition can contain water, butit also may be anhydrous, if desired.

According to preferred embodiments of the present invention, thecompositions are solid. The solid nature of the compositions can bedetermined by determining the hardness of the compositions. The hardnessof a composition may, for example, be expressed in gramforce (gf). Solidcompositions of the present invention may, for example, have a hardnessranging from 20 gf to 2000 gf, such as from 20 gf to 900 gf, and furthersuch as from 20 gf to 600 gf.

This hardness is measured in one of two ways. A first test for hardnessis according to a method of penetrating a probe into the composition andin particular using a texture analyzer (for example TA-XT2i from Rheo)equipped with an ebonite cylinder of height 25 mm and diameter 8 mm. Thehardness measurement is carried out at 20° C. at the center of 5 samplesof the composition. The cylinder is introduced into each sample ofcomposition at a pre-speed of 2 mm/s and then at a speed of 0.5 mm/s andfinally at a post-speed of 2 mm/s, the total displacement being 1 mm.The recorded hardness value is that of the maximum peak observed. Themeasurement error is ±50 gf.

The second test for hardness is the “cheese wire” method, which involvescutting an 8.1 mm or preferably 12.7 mm in diameter stick compositionand measuring its hardness at 20° C. using a DFGHS 2 tensile testingmachine from Indelco-Chatillon Co. at a speed of 100 mm/minute. Thehardness value from this method is expressed in grams as the shear forcerequired to cut a stick under the above conditions. According to thismethod, the hardness of compositions according to the present inventionwhich may be in stick form may, for example, range from 30 gf to 300 gf,such as from 30 gf to 250 gf, for a sample of 8.1 mm in diameter stick,and further such as from 30 gf to 200 gf, and also further such as from30 gf to 120 gf for a sample of 12.7 mm in diameter stick.

When the compositions are solid, the hardness of the composition of thepresent invention is such that the compositions are self-supporting butcan easily form a satisfactory deposit on a keratinous material. Inaddition, this hardness imparts good impact strength to the inventivecompositions, which can be molded or cast, for example, in stick or dishform.

The skilled artisan may choose to evaluate a composition using at leastone of the tests for hardness outlined above based on the applicationenvisaged and the hardness desired. If one obtains an acceptablehardness value, in view of the intended application, from at least oneof these hardness tests, the composition falls within preferredembodiments of the invention.

As defined herein, stability is tested by placing the composition in acontrolled environment chamber for 8 weeks at 25° C. In this test, thephysical condition of the sample is inspected as it is placed in thechamber. The sample is then inspected again at 24 hours, 3 days, 1 week,2 weeks, 4 weeks and 8 weeks. At each inspection, the sample is examinedfor abnormalities in the composition such as phase separation if thecomposition is in the form of an emulsion, bending or leaning if thecomposition is in stick form, melting, or syneresis (or sweating). Thestability is further tested by repeating the 8-week test at 40° C., 37°C., 45° C., 50° C. and under freeze-thaw conditions. A composition isconsidered to lack stability if in any of these tests an abnormalitythat impedes functioning of the composition is observed. The skilledartisan will readily recognize an abnormality that impedes functioningof a composition based on the intended application.

In accordance with preferred embodiments of the present invention,compositions comprising at least one polyorganosiloxane-containingpolymer, at least one volatile non-silicone oil, at least one alkylenepolymer wax and at least one silicone film forming agent are provided.

In this case, the copolymer may correspond to the formula:

in which R¹ to R⁴, X, Y, m₁, m₂, n and p have the meanings given aboveand Y¹ is different from Y but chosen from the groups defined for Y. Aspreviously discussed, the various moieties may be structured to formeither a block copolymer, or a random copolymer or an alternatingcopolymer.

In an embodiment of the invention, the polyorganosiloxane-containingpolymer may also contain a grafted copolymer. Thus, the polyamidecontaining silicone units may be grafted and optionally crosslinked withsilicone chains containing amide groups. Such polymers may besynthesized with trifunctional amines.

In this case, the copolymer may comprise at least one moiety of formula:

in which X¹ and X², which may be identical or different, have themeaning given for X in formula (I), n is as defined in formula (I), Yand T are as defined in formula (I), R¹¹ to R¹⁸ are groups chosen fromthe same group as R¹ to R⁴, m₁ and m₂ are numbers in the range from 1 to1,000, and p is an integer of at least one, for example, p can rangefrom 2 to 500.

in particular with R²⁰, R²¹ and R²² representing —CH₂—CH₂—,

m₁ and m₂ are in the range from 15 to 500, including from 15 to 45 andincluding all values and subranges there between,

X¹ and X² represent —(CH₂)₁₀—, and

Y represents —CH₂—.

These polyamides containing a grafted silicone moiety of formula (VII)may be copolymerized with polyamide-silicones of formula (II) to formblock copolymers, alternating copolymers or random copolymers. Theweight percentage of grafted silicone moieties (VII) in the copolymermay range from 0.5% to 30% by weight.

According to the invention, as has been seen previously, the siloxaneunits may be in the main chain or backbone of the polymer, but they mayalso be present in grafted or pendent chains. In the main chain, thesiloxane units may be in the form of segments as described above. In thependent or grafted chains, the siloxane units may appear individually orin segments.

According to the invention, the preferred siloxane-based polyamides are:

polyamides of formula (III) in which m is from 15 to 300, for example,15 to 100, including all values and subranges there between;

mixtures of two or more polyamides in which at least one polyamide has avalue of m in the range from 15 to 50, including all values andsubranges there between and at least one polyamide has a value of m inthe range from 30 to 300, including all values and subranges therebetween;

mixtures of polyamide of formula (III) combining

1) 80% to 99% by weight of a polyamide in which n is equal to 2 to 10and in particular 3 to 6, and

2) 1% to 20% of a polyamide in which n is in the range from 5 to 500 andin particular from 6 to 100;

polyamides corresponding to formula (VI) in which at least one of thegroups Y and Y¹ contains at least one hydroxyl substituent;

polyamides of formula (III) synthesized with at least one portion of anactivated diacid (diacid chloride, dianhydride or diester) instead ofthe diacid;

polyamides of formula (III) in which X represents —(CH₂)₃— or —(CH₂)₁₀;and

polyamides of formula (III) in which the polyamides end with amonofunctional chain chosen from the group consisting of monofunctionalamines, monofunctional acids, monofunctional alcohols, including fattyacids, fatty alcohols and fatty amines, such as, for example,octylamine, octanol, stearic acid and stearyl alcohol.

According to the invention, the end groups of the polymer chain may endwith:

a C₁ to C₅₀ alkyl ester group by introducing a C₁ to C₅₀ monoalcoholduring the synthesis,

a C₁ to C₅₀ alkylamide group by taking as stopping group a monoacid ifthe silicone is □,ω-diaminated, or a monoamine if the silicone is an□,ω-dicarboxylic acid.

According to one embodiment of the invention, it is possible to use acopolymer of silicone polyamide and of hydrocarbon-based polyamide, i.e.a copolymer comprising moieties of formula (III) or (IV) andhydrocarbon-based polyamide moieties. In this case, thepolyamide-silicone moieties may be arranged at the ends of thehydrocarbon-based polyamide.

Polyamide-based polymers containing silicones may be produced by silylicamidation of polyamides based on fatty acid dimer. This approachinvolves the reaction of free acid sites existing on a polyamide as endsites, with organosiloxane-monoamines and/or organosiloxane-diamines(amidation reaction), or alternatively with oligosiloxane alcohols oroligosiloxane diols (esterification reaction). The esterificationreaction requires the presence of acid catalysts, as is known in theart. It is desirable for the polyamide containing free acid sites, usedfor the amidation or esterification reaction, to have a relatively highnumber of acid end groups (for example polyamides with high acidnumbers, for example from 15 to 20).

For the amidation of the free acid sites of the hydrocarbon-basedpolyamides, siloxane diamines with 1 to 300, more particularly 2 to 50and for example, 2, 6, 9.5, 12, 13.5, 23 or 31 siloxane groups, may beused for the reaction with hydrocarbon-based polyamides based on fattyacid dimers. Siloxane diamines containing 13.5 siloxane groups arepreferred, and the best results are obtained with the siloxane diaminecontaining 13.5 siloxane groups and polyamides containing high numbersof carboxylic acid end groups.

The reactions may be carried out in xylene to extract the water producedfrom the solution by azeotropic distillation, or at higher temperatures(about 180 to 200° C.) without solvent. Typically, the efficacy of theamidation and the reaction rates decrease when the siloxane diamine islonger, that is to say when the number of siloxane groups is higher.Free amine sites may be blocked after the initial amidation reaction ofthe diaminosiloxanes by reacting them either with a siloxane acid, orwith an organic acid such as benzoic acid.

For the esterification of the free acid sites on the polyamides, thismay be performed in boiling xylene with about 1% by weight, relative tothe total weight of the reagents, of para-toluenesulphonic acid ascatalyst.

These reactions carried out on the carboxylic acid end groups of thepolyamide lead to the incorporation of silicone moieties only at theends of the polymer chain.

It is also possible to prepare a copolymer of polyamide-silicone, usinga polyamide containing free amine groups, by amidation reaction with asiloxane containing an acid group.

It is also possible to prepare a gelling agent based on a copolymerbetween a hydrocarbon-based polyamide and a silicone polyamide, bytransamidation of a polyamide having, for example, an ethylene-diamineconstituent, with an oligosiloxane-□,ω-diamine, at high temperature (forexample 200 to 300° C.), to carry out a transamidation such that theethylenediamine component of the original polyamide is replaced with theoligosiloxane diamine.

The copolymer of hydrocarbon-based polyamide and of polyamide-siliconemay also be a grafted copolymer comprising a hydrocarbon-based polyamidebackbone with pendent oligosiloxane groups.

This may be obtained, for example:

by hydrosilylation of unsaturated bonds in polyamides based on fattyacid dimers;

by silylation of the amide groups of a polyamide; or

by silylation of unsaturated polyamides by means of an oxidation, thatis to say by oxidizing the unsaturated groups into alcohols or diols, toform hydroxyl groups that are reacted with siloxane carboxylic acids orsiloxane alcohols. The olefinic sites of the unsaturated polyamides mayalso be epoxidized and the epoxy groups may then be reacted withsiloxane amines or siloxane alcohols.

The polyorganosiloxane containing polymers used in the composition ofthe invention are most preferably polymers of the polyorganosiloxanetype such as those described in documents U.S. Pat. No. 5,874,069, U.S.Pat. No. 5,919,441, U.S. Pat. No. 6,051,216 and U.S. Pat. No. 5,981,680,the entire disclosures of which are hereby incorporated by reference.

According to another embodiment of the invention, the polyorganoxiloxanecontaining polymer is a homopolymer or a copolymer comprising urethaneor urea groups.

As previously discussed, the polymer may comprise polyorganosiloxanemoieties containing two or more urethane and/or urea groups, either inthe backbone of the polymer or on side chains or as pendent groups.

The polymers comprising at least two urethane and/or urea groups in thebackbone may be polymers comprising at least one moiety corresponding tothe following formula:

in which R¹, R², R³, R⁴, X, Y, m and n have the meanings given above forformula (I), and U represents —O— or —NH—, such that:

corresponds to a urethane or urea group.

In this formula (VIII), Y may be a linear or branched C₁ to C₄₀ alkylenegroup, optionally substituted with a C₁ to C₁₅ alkyl group or a C₅ toC₁₀ aryl group. Preferably, a —(CH₂)₆— group is used.

Y may also represent a C₅ to C₁₂ cycloaliphatic or aromatic group thatmay be substituted with a C₁ to C₁₅ alkyl group or a C₅ to C₁₀ arylgroup, for example a radical chosen from the methylene-4,4-biscyclohexylradical, the radical derived from isophorone diisocyanate, 2,4- and2,6-tolylenes, 1,5-naphthylene, p-phenylene and 4,4′-biphenylenemethane.Generally, it is preferred for Y to represent a linear or branched C₁ toC₄₀ alkylene radical or a C₄ to C₁₂ cycloalkylene radical.

Y may also represent a polyurethane or polyurea block corresponding tothe condensation of several diisocyanate molecules with one or moremolecules of coupling agents of the diol or diamine type. In this case,Y comprises several urethane or urea groups in the alkylene chain.

It may correspond to the formula:

in which B¹ is a group chosen from the groups given above for Y, U is—O— or —NH— and B² is chosen from:

linear or branched C₁ to C₄₀ alkylene groups, which can optionally bearan ionizable group such as a carboxylic acid or sulphonic acid group, ora neutralizable or quaternizable tertiary amine group,

C₅ to C₁₂ cycloalkylene groups, optionally bearing alkyl substituents,for example one to three methyl or ethyl groups, or alkylene, forexample the diol radical: cyclohexanedimethanol,

phenylene groups that may optionally bear C₁ to C₃ alkyl substituents,and

groups of formula:

in which T is a hydrocarbon-based trivalent radical possibly containingone or more hetero atoms such as oxygen, sulphur and nitrogen and R⁵ isa polyorganosiloxane chain or a linear or branched C₁ to C₅₀ alkylchain.

T can represent, for example:

with w being an integer ranging from 1 to 10 and R⁵ being apolyorganosiloxane chain.

When Y is a linear or branched C₁ to C₄₀ alkylene group, the —(CH₂)₂—and —(CH₂)₆— groups are preferred.

In the formula given above for Y, d may be an integer ranging from 0 to5, preferably from 0 to 3 and more preferably equal to 1 or 2.

Preferably, B² is a linear or branched C₁ to C₄₀ alkylene group, inparticular —(CH₂)₂— or —(CH₂)₆— or a group:

with R⁵ being a polyorganosiloxane chain.

As previously discussed, the polyorganosiloxane containing polymer maybe formed from silicone urethane and/or silicone urea moieties ofdifferent length and/or constitution, and may be in the form of block orrandom copolymers.

According to the invention, the silicone may also comprise urethaneand/or urea groups no longer in the backbone but as side branches.

In this case, the polymer may comprise at least one moiety of formula:

in which R¹, R², R³, m₁ and m₂ have the meanings given above for formula(I),

U represents O or NH,

R²³ represents a C₁ to C₄₀ alkylene group, optionally comprising one ormore hetero atoms chosen from O and N, or a phenylene group, and

R²⁴ is chosen from linear, branched or cyclic, saturated or unsaturatedC₁ to C₅₀ alkyl groups, and phenyl groups optionally substituted withone to three C₁ to C₃ alkyl groups.

The polymers comprising at least one moiety of formula (X) containsiloxane units and urea or urethane groups, and they may be used, forexample, as gelling agents in the compositions of the invention.

The siloxane polymers may have a single urea or urethane group bybranching or may have branches containing two urea or urethane groups,or alternatively they may contain a mixture of branches containing oneurea or urethane group and branches containing two urea or urethanegroups.

They may be obtained from branched polysiloxanes, comprising one or twoamino groups by branching, by reacting these polysiloxanes withmonoisocyanates.

As examples of starting polymers of this type containing amino anddiamino branches, mention may be made of the polymers corresponding tothe following formulae:

In these formulae, the symbol “/” indicates that the segments may be ofdifferent lengths and in a random order, and R represents a linearaliphatic group preferably containing 1 to 6 carbon atoms, including 1to 3 carbon atoms.

Such polymers containing branching may be formed by reacting a siloxanepolymer, containing at least three amino groups per polymer molecule,with a compound containing only one monofunctional group (for example anacid, an isocyanate or an isothiocyanate) to react this monofunctionalgroup with one of the amino groups and to form groups capable ofestablishing hydrogen interactions. The amino groups may be on sidechains extending from the main chain of the siloxane polymer, such thatthe groups capable of establishing hydrogen interactions are formed onthese side chains, or alternatively the amino groups may be at the endsof the main chain, such that the groups capable of hydrogen interactionwill be end groups of the polymer.

As a procedure for forming a polymer containing siloxane units andgroups capable of establishing hydrogen interactions, mention may bemade of the reaction of a siloxane diamine and of a diisocyanate in asilicone solvent so as to provide a gel directly. The reaction may beperformed in a silicone fluid, the resulting product being dissolved inthe silicone fluid, at high temperature, the temperature of the systemthen being reduced to form the gel.

The polymers that are preferred for incorporation into the compositionsaccording to the present invention are siloxane-urea copolymers that arelinear and that contain urea groups as groups capable of establishinghydrogen interactions in the backbone of the polymer.

As an illustration of a polysiloxane ending with four urea groups,mention may be made of the polymer of formula:

in which Ph is a phenyl group and n is a number larger than 0, whichincludes, at least 1, 2 to 500, 2 to 200, from 1 to 300, in particularfrom 1 to 100, and all values and subranges there between, for example50.

This polymer is obtained by reacting the following polysiloxanecontaining amino groups:

with phenyl isocyanate.

The polymers of formula (VIII) comprising urea or urethane groups in thechain of the silicone polymer may be obtained by reaction between asilicone containing □,ω-NH₂ or —OH end groups, of formula:

in which m, R¹, R², R³, R⁴ and X are as defined for formula (I) and adiisocyanate OCN—Y—NCO in which Y has the meaning given in formula (I);and optionally a diol or diamine coupling agent of formula H₂N—B²—NH₂ orHO—B²—OH, in which B² is as defined in formula (IX).

According to the stoichiometric proportions between the two reagents,diisocyanate and coupling agent, Y may have the formula (IX) with dequal to 0 or d equal to 1 to 5.

As in the case of the polyamide silicones of formula (II) or (III), itis possible to use in the invention polyurethane or polyurea siliconescontaining moieties of different length and structure, in particularmoieties whose lengths differ by the number of silicone units. In thiscase, the copolymer may correspond, for example, to the formula:

in which R¹, R², R³, R⁴, X, Y and U are as defined for formula (VIII)and m₁, m₂, n and p are as defined for formula (V).

Branched polyurethane or polyurea silicones may also be obtained using,instead of the diisocyanate OCN—Y—NCO, a triisocyanate of formula:

A polyurethane or polyurea silicone containing branches comprising anorganosiloxane chain with groups capable of establishing hydrogeninteractions is thus obtained. Such a polymer comprises, for example, amoiety corresponding to the formula:

in which X¹ and X², which are identical or different, have the meaninggiven for X in formula (I), n is as defined in formula (I), Y and T areas defined in formula (I), R¹¹ to R¹⁸ are groups chosen from the samegroup as R¹ to R⁴, m₁ and m₂ are as defined above.

As in the case of the polyamides, this copolymer can also comprisepolyurethane silicone moieties without branching.

In another embodiment of the invention, the siloxane-based polyureas andpolyurethanes that are preferred are:

1) 80% to 99% by weight of a polymer in which n is equal to 2 to 10 andin particular 3 to 6, and

2) 1% to 20% of a polymer in which n is in the range from 5 to 500 andin particular from 6 to 100,

copolymers comprising two moieties of formula (VIII) in which at leastone of the groups Y contains at least one hydroxyl substituent;

polymers of formula (VIII) synthesized with at least one portion of anactivated diacid (diacid chloride, dianhydride or diester) instead ofthe diacid;

As in the case of the polyamides, copolymers of polyurethane or polyureasilicone and of hydrocarbon-based polyurethane or polyurea may be usedin the invention by performing the reaction for synthesizing the polymerin the presence of an □,ω-difunctional block of non-silicone nature, forexample a polyester, a polyether or a polyolefin.

As has been seen previously, homopolymers or copolymers of the inventionmay contain siloxane moieties in the main chain of the polymer andgroups capable of establishing hydrogen interactions, either in the mainchain of the polymer or at the ends thereof, or on side chains orbranches of the main chain. This may correspond to the following fivearrangements:

in which the continuous line is the main chain of the siloxane polymerand the squares represent the groups capable of establishing hydrogeninteractions.

In case (1), the groups capable of establishing hydrogen interactionsare arranged at the ends of the main chain.

In case (2), two groups capable of establishing hydrogen interactionsare arranged at each of the ends of the main chain.

In case (3), the groups capable of establishing hydrogen interactionsare arranged within the main chain in repeating moieties.

In cases (4) and (5), these are copolymers in which the groups capableof establishing hydrogen interactions are arranged on branches of themain chain of a first series of moieties that are copolymerized withmoieties not comprising groups capable of establishing hydrogeninteractions. Preferably, the values n, x and y are such that thepolymer has the desired properties in terms of an agent for gellingfatty phases, preferably fatty phases based on silicone oil.

As examples of polymers that may be used, mention may be made of thesilicone polyamides obtained in accordance with the disclosure in U.S.Pat. No. 5,981,680, the entire disclosure of which is herebyincorporated by reference.

Most preferably, they have asoftening point ranging from 65 to 150° C., including from 70° C. to130° C. This softening point is lower than that of other structuringpolymers, which facilitates the use of the polymers that are the subjectof the invention, and limits the deteriorations of the liquid fattyphase.

As noted above, the polyorganosiloxane containing polymers of thepresent invention contain both siloxane units and at least two groupscapable of establishing hydrogen interactions such as amide linkages.The siloxane units can provide compatibility with a silicone fluid, ifpresent, (for example with the cyclomethicones), while the groupscapable of establishing hydrogen interactions and the spacing andselection of the locations of the amide linkages can facilitate gelationand the formation of cosmetic products.

Silicone Film Forming Agents

According to preferred embodiments, the composition comprises one ormore silicone film forming agents. Preferably, the at least one siliconefilm forming agent is a silicone resin film forming agent such as an MKor an MQ resin, or mixtures thereof.

Silicone resin nomenclature is known in the art as “MDTQ” nomenclature,whereby a silicone resin is described according to the various monomericsiloxane units which make up the polymer.

Each letter of “MDTQ” denotes a different type of unit. The letter Mdenotes the monofunctional unit (CH₃)₃SiO_(1/2). This unit is consideredto be monofunctional because the silicone atom only shares one oxygenwhen the unit is part of a polymer. The “M” unit can be represented bythe following structure:

At least one of the methyl groups of the M unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2), asrepresented in the following structure:

wherein R is chosen from groups other than methyl groups. Non-limitingexamples of such groups other than methyl groups include alkyl groupsother than methyl groups, alkene groups, alkyne groups, hydroxyl groups,thiol groups, ester groups, acid groups, ether groups, wherein thegroups other than methyl groups may be further substituted.

The symbol D denotes the difunctional unit (CH₃)₂SiO_(2/2) wherein twooxygen atoms bonded to the silicone atom are used for binding to therest of the polymer. The “D” unit, which is the major building block ofdimethicone oils, can be represented as:

At least one of the methyl groups of the D unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

The symbol T denotes the trifunctional unit, (CH₃)SiO_(3/2) and can berepresented as:

At least one of the methyl groups of the T unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

Similarly, the symbol Q denotes the tetrafunctional unit, SiO_(4/2)wherein all four oxygens bonded to the silicone atom are bonded to therest of the polymer.

Thus, a vast number of different silicone polymers can be manufactured.Further, it would be clear to one skilled in the art that the propertiesof each of the potential silicone polymers will vary depending on thetype(s) of monomer(s), the type(s) of substitution(s), the size of thepolymeric chain, the degree of cross linking, and size of any sidechain(s).

Non-limiting examples of silicone polymers include silanes, siloxanes,siloxysilicates, and silsesquioxanes. A non-limiting example of such asiloxane is polydimethylsiloxane (PDMS). Polydimethylsiloxanes aregenerally composed of long straight chains of (CH₃)₂SiO_(2/2) (i.e., Dunits) and have viscosities which are dependent on both the size of thepolymer and the presence and nature of any substituent(s) on thepolymer. A non-limiting example of a siloxysilicate istrimethylsiloxysilicate, which may be represented by the followingformula:[(CH₃)₃—Si—O]_(x)—(SiO_(4/2))_(y)

(i.e., MQ units) wherein x and y may, for example, range from 50 to 80.Silsesquioxanes, on the other hand, may be represented by the followingformula:(CH₃SiO_(3/2))_(.x)

(i.e., T Units) wherein x may, for example, have a value of up toseveral thousand.

Polymethylsilsesquioxanes are silsesquioxanes that do not have asubstituent replacing the methyl groups. Certainpolymethylsilsesquioxanes have previously been used in hair carecompositions. See, e.g., U.S. Pat. No. 5,246,694, the disclosure ofwhich is incorporated herein by reference, which discloses a shampoocomposition comprising a surfactant, an aqueous emulsion of highlyviscous silicone in volatile silicone and a cationic polymer which is aderivative of guar gum. The highly viscous silicone disclosed thereinmay be chosen from silicone resins including a polymethylsilsesquioxanesuch as Resin MK (also called SiliconHarz MK) which is available fromWacker, and a siloxysilicate such as Resin MQ which is available fromGeneral Electric and Dow Corning.

The Resin MK and Resin MQ silicone resins may form a film after avolatile carrier has evaporated. The MQ film is generally hard andbrittle at room temperature, while the MK film is generally continuousand flexible, i.e., not brittle. Depending on the application,plasticizers may be added to help obtain a more flexible, thus morecomfortable, film.

In one embodiment, the silicone film former may be apolymethylsilsesquioxane film former such as Belsil PMS MK, alsoreferred to as Resin MK, available from Wacker Chemie. Thispolymethylsilsesquioxane film former is a polymer comprising polymerizedrepeating units of CH₃SiO_(3/2) (T units) and may also contain up to 1%by weight or by mole of units of the formula (CH₃)₂SiO_(2/2) (D units).The weight-average molecular weight of this polymer has been estimatedto be 10,000. It is believed that the polymers are in a “cage” and“ladder” configuration, as exemplified in the figures below. Themajority of the polymer is in the “ladder” configuration, wherein theends of the polymer are capped with ethoxy (CH₃CH₂O) groups. The ethoxygroups are generally present in an amount of 4.5% by weight and the molepercent is generally 7% (silicone units). As ethoxy groups may reactwith water, a small and variable amount of SiOH may also be present inthe polymer.

Another non-limiting example of the at least onepolymethylsilsesquioxane film former suitable for use in the presentinvention is KR-220L, which is available from SHIN-ETSU. Thispolymethylsilsesquioxane film former is composed of silicone T-units(i.e., those of formula CH₃SiO_(3/2)) and has Si—OH (or silanol) endunits. There are no D units in KR-220L.

Other non-limiting examples of the at least one polymethylsilsesquioxanefilm former that may be useful in the practice of the invention includeKR-242A (which is comprised of methyl T units (98%) and dimethyl D units(2%) and has Si—OH end units) and KR-251 (which is comprised of methyl Tunits (88%) and dimethyl D units (12%) and has Si—OH end units), both ofwhich are available from SHIN-ETSU.

Depending on the application, the concentration of the at least onepolymethylsilsesquioxane film former in the presently claimedcomposition may vary considerably. One of skill in the art will be ableto determine routinely the amount of the at least onepolymethylsilsesquioxane film former depending on the desiredapplication.

In another embodiment, the silicone film former may be chosen fromsiloxysilicates. Preferably, the siloxysilicate istrimethylsiloxysilicate, which may or may not be in powder form.Trimethylsiloxysilicate (TMS) is commercially available from GeneralElectric under the tradename SR1000 and from Wacker under the tradenameTMS 803. TMS is also commercially available from Dow Chemical in asolvent, such as for example, cyclomethicone. However, according to thepresent invention, TMS may be used in the form of 100% active material,that is, not in a solvent.

Further non-limiting examples of the silicone film formers includesilicone/(meth)acrylate copolymers, such as those as described in U.S.Pat. Nos. 5,061,481, 5,219,560, and 5,262,087, the disclosures of whichare hereby incorporated by reference. Still further non-limitingexamples of silicone film formers are non-polar silicone copolymerscomprising repeating units of at least one polar (meth)acrylate unit andvinyl copolymers grafted with at least one non-polar silicone chain.Non-limiting examples of such copolymers are acrylates/dimethiconecopolymers such as those commercially available from Shin-Etsu, forexample, the product sold under the tradename KP-545, oracrylates/stearyl acrylate/dimethicone acrylates copolymers, such asthose commercially available from Shin-Etsu, for example, the productsold under the tradename KP-561, and acrylates/behenylacrylate/dimethicone acrylates copolymer, such as those commerciallyavailable from Shin-Etsu, for example, the product sold under thetradename KP-562.

-   1. Combine Phase A ingredients together, then transfer to the beaker    to a 100° C. oil bath and mix with a propeller mixer until the    solution completely uniform.-   2. Combine Phase B ingredients together into Phase A, then mix until    the waxes melted.-   3. Add Phase C ingredients into Phase (A+B) solution and mix for    about 10 minutes with high speed of mixer rotation.-   4. Add phase D into phase (A+B+C) and mix with high speed for 15    minutes.-   5. Reduce temperature down to 90-95° C., continue mixing at low    speed, for 5-10 minutes-   6. Transfer the resulting fluid to the mold at room temperature.-   7. After cool at room temperature about 10 minutes, put the mold in    the freezer for 40 minutes.    Procedure of Preparing Phase C (Color Grind)-   1. Combine Phase C ingredients together, then mix by hand until    pigments are totally wet, then use high speed mixer to mix about 10    minutes.-   2. Transfer the mixture to the Disconti-Mill and mill for 1 hour    until the color grind becomes homogeneous.-   3. Transfer the color grind phase C into the container for use in    the procedure above.    Procedure for Determining Hardness

The procedure used for determining hardness is set forth herein above.

Procedure for Determining Wear

The lip compositions were applied to the lips of 6 panelists. The lipswere photographed before, and immediately after, application usingdiffuse lighting in a device such as the one described and claimed inUS20030067545, the entire contents of which are incorporated byreference, and the images analyzed for L* color value. The L* colorvalue indicates the darkness or intensity of the color. The panelistswere then asked to eat a meal consisting of a sandwich, a salad and ahot beverage. The lips of the panelists were photographed after the mealusing the device above, and the images analyzed for L* color value. Thewear is reported as % wear and indicates how much of the compositionremains on the lips.
